An effective non-combustible fire wall is designed to prevent the spread of fire between different areas of a building or between different buildings. One of the main features of such fire walls is their designated fire resistance rating, which indicates how long they can withstand exposed flames before failing. This rating is crucial in ensuring safety and protecting property.

Insulation properties are also essential for fire walls; they help to limit heat transfer and maintain a safe environment on the non-fire side of the wall. Insulation plays a significant role in enhancing the overall effectiveness of the fire wall.

The spacing between building structures is related to fire safety but is influenced by building codes and regulations rather than being a characteristic of the fire wall itself. This spacing helps reduce fire risks but does not specifically pertain to the fire wall’s non-combustible properties.

In this context, the duration of exposed flames does not accurately describe a feature of a fire wall. The design of fire walls is not about the flames themselves but about how well the wall can resist them, making this characteristic the one that stands out as not fitting with the typical features of a non-combustible fire wall.
